Recently, I found serenditpitously an old, solar-powered pocket
calculator.  I remember buying it as least fifteen - and maybe twenty -
years ago.  It still works!  The problem is, I can't remember the key
functions.  The case says it's a Texas Instruments calculator, and the
plastic case was made in China (isn't everything?). There's no model
number, but the keys are "2nd, %, DRG, CE/C, AC/ON, 1/x, SIN, COS, TAN,
y (to the xth power), x!, EE, LOG, LN, division, x (square), K, (, ),
and x.

The number keys are accompanied and grouped with STO, RCL, SUM, and EXC
- along with+/- and the equal sign.

Does anybody have the instructions for key function?  We have a couple
of additional calculators, but the keys are different - as are
functions.

Thanks,
